Isabella "Bella" Swan (played by Kristen Stewart)
The series' narrator is a fair-skinned brunette who moves in with her father, the chief of police in Forks, Washington, during her junior year of high school. Bella is described as clumsy and stubborn, and she faints at the sight of blood. Despite her male classmates' best efforts, she only has eyes for one boy, Edward Cullen.

Edward Cullen
(played by Robert Pattinson)
As a vampire, Edward is impossibly beautiful, strong and fast, but he wasn't always this way. Edward was born in 1901, and at age 17, he contracted Spanish influenza. As he lay on his deathbed, Dr. Carlisle Cullen transformed him into a vampire to prevent him from dying.

Dr. Cullen teaches Edward to live as a "vegetarian" vampire, which means drinking the blood of animals instead of humans. Over time, Edward develops a taste for mountain lion. Edward doesn't sleep or eat human food, but he can read minds and play the piano.
